What Diners Say

★★★★ "The Old Siam is conveniently located on the corner of Ellis and Mason streets in downtown area (two walking blocks away from Powell Street Subway Station) that is surrounded by hotels imhv should be regarded one of the few best authentic affordable Thai restaurants left in The City.

★★★ "The restaurant was quite busy, yet the service remained efficient and attentive. Despite the crowd, the food arrived quickly.

★★★★ "If you’re looking for authentic Thai food, you should definitely go. The flavors are truly Thai. Personally, I didn’t love it, but that’s mainly because I’m not really a fan of Thai food in general. Objectively, I think they serve good-quality food.
